both options "C" and "D" are correct in my opinion cause as the car is moving at a constant speed there is no acceleration and as the car is being ridden on a straight road direction of movement also does not change, Hence proving that both option "C" and "D" are correct. I hope my answer was helpful. A very Happy New Year to all

Class : Class 7
Both option C and option D are correct as since it is moving in constant speed, it's acceleration will be zero and the direction will not change as it was not mentioned and the particle is travelling on a straight road

Hydrocloric acid is very corrosive and reacts with metals . So HCL is stored in glass bottles because it dont causes damage to it . ..........SO 3 statement should be true and their explanation is wrong .
